So if your going to force people to purchase games with copy protection via snail mail why not do the smart thing to increase your profits. F*ck the box, load up a torrent of the game and sell the serial. Hell even put up just the binary as an alternative option if they already have the game to download because you don't have to worry about the packaging/shipping costs and people get rather instant gratification from their purchase. Saving all that money on not having to press DVD's and packaging would only make it that more profitable or you could also just pass those savings on to the consumer.
If your going to force the customer to be authenicated online there is no need to charge the consumer for the expenses of a retail box.
